FAQ
- Abnormal power indicator (PWR)
No light: First, check whether the power connection and device power supply are normal; Second, check whether the power switch on the rear panel of the device is on. If the problem is not solved, please contact the distributor or manufacturer.
- Abnormal status indicator (SYS)
After 18 seconds of power-on, the system is working normally and the system light of the device should be flashing once per second.
Does not light up, often light up, or blinks rapidly:
First, system error, contact the after-sales service to upgrade the software version; Second, long press the reset button (R hole on the rear panel of the device) for more than 6 seconds, the device will restore the factory settings and restart automatically. If the problem is not solved, please contact the distributor or manufacturer.
- Channel no sound
First, check whether the audio source, audio input and output wiring is normal; Second, check whether the mute function of the corresponding audio channel is enabled, if the mute switch has been turned on, please turn off the mute switch; Third, check whether the settings of the corresponding channel’s input processing, matrix mixing and output processing are normal. If the problem is not solved, please contact the distributor or manufacturer.
- The control software cannot search the device
First, check whether the system light of the device is in normal blinking state; Second, check whether the network connection is normal; Third, ensure the network accessibility between the configuration host and the device; Fourth, press and hold down the reset button (R-hole on the rear panel of the device) for more than 6 seconds, and the device will restore the factory settings and restart automatically. If the problem is not solved, please contact the distributor or manufacturer.
- Network connection failure
Network connection failure is usually caused by different network segments of the device. If the LAN and the processor network segments are different, you can connect the processor directly via PC, login to the device configuration interface, change the processor network segment to be the same as the LAN and then access the LAN. (Note: If the LAN is automatically obtaining IP, please check DHCP).
- Current noise in output channel
Please check whether the processor is well grounded, which usually requires the grounding screw on the left side of the rear panel of the chassis to be connected to the metal enclosure such as the cabinet through a metal wire. If the problem still exists, please check the wiring of the input devices. If the input devices are unbalanced (two wires), please connect the “+” and “G” of the input connector of the processor.
- How to recognize system noise
After the system is set up, there is noise troubleshooting: First, unplug the device output audio cable, there is noise, please check the causes of the back stage equipment; Second, restore the output wiring, mute the corresponding output channel, there is noise, if unbalanced connection, try to shorten the connecting line, to avoid the introduction of interference, if balanced connection, try to disconnect the ground wire; Third, cancel the corresponding channel mute, unplug the device input audio cable, there is noise, long press the reset button (R hole on the rear panel of the device) for more than 6 seconds, the device will restore the factory settings and restart automatically;Fourth, restore the input wiring, turn off the audio source, there is noise, check the input connection, refer to the second point of the processing; Fifth, check the audio source is there is noise. If the problem is not solved, please contact the distributor or manufacturer.
- RS232 center control command does not work
First, check whether the connection is normal, the central control host TX connected to the device’s RX, the central control host RX connected to the device’s TX, the central control host and the device’s ground inter connect; Second, check the software configuration of the device interface items: baud rate, start bit, stop bit, etc. Settings are the same as the interface configuration of the central control host. If the problem is not solved, please contact the distributor or manufacturer.
- U disk audio can not be played
The device only supports FAT32 format U disk, only supports MP3 or WAV format audio files, audio files need to be stored in the root directory; ensure that the U disk is writable, the device needs to create a playlist. U disk has more than one partition only recognizes the first partition.
